The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing. I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

Purpose: The purpose of this paper is to examine if companies? incentive programs for employees is designed in such a way that it makes it possible for managers to reach their goals. Method: Qualitative with a semi standardised questionnaire Results: Our results is that the incentive programs for employees in their present form don?t give the companies a good possibility to effect the employees to perform towards the goals of the system. The performance measures in the incentive programs for employees is suitable in comparison with the goals of the program but the construction and the use of the systems doesn?t give a satisfied result in comprising with the goals.

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained.

Under senare tid har det på den svenska livsmedelsmarknaden växt olika miljö- och kvalitetsmärkningar som grundar sig på olika kriterier. Vi har i denna uppsats valt att studera två av dessa: Svenskt Sigill coh SVENSKODLAT. Syftet med denna uppsats är därför att ur ett producentperspektiv, undersöka huruvida Svenskt Sigill och SVENSKODLAT certifieringarna kan utgöra en strategisk konkurrensfördel. Vi har identifierat tre aspekter som var och en i varierande grad kan sägas bidra till att de båda certifieringar vi studerat skapar konkurrensfördelar. Dessa tre aspekter vilka vi sammanfattat i en ABC-modell är: adding value, barrier to entry och cost saving.

The purpose of this paper is to explore how masculinity and femininity are constructed in the magazine Veckorevyn, through a critical discourse analysis of 18 articles from six issues in 2011. This is done by using a variety of theories and previous research results, which is gender theory, the theory of late-modern society and media theory. The analysis shows that Veckorevyn depicts virility and feminine differently. Furthermore, pointing the results from the analysis that a change of manhood and womanhood takes place in the social practice. The selection of articles from the magazine also shows that Veckorevyn seems to promote gender equality. .

PURPOSE: To analyze how companies in the Swedish beer industry strategically workingwith CSR externally in order to increase their legitimacy.METHOD: Qualitative interviews and text analysis to enable data to stakeholder analysis.MATERIAL: Respondent interviews with key individuals, textual analysis of CSR-relateddocuments of the largest beer producers in Sweden.MAIN RESULTS: The study shows that it is possible to distinguish three main categories ofstakeholders to the beer producers. These have various high stakeholder values, wherecustomers are those with the highest value, then consumers and third critics. That these havevarious high values allows different strategic approach to the key issue of how preventivemeasures, that can be said to work against their own products, affects the beer producerslegitimacy among stakeholders..

The financial crisis in the beginning of the 1990´s the financial crisis had a strong impact on the Swedish economy. Some of the main actors in the crisis were the largest banks of Sweden which brought a huge amount of losses on themselves. One of the main reasons for this was that the banks focused on volume increases rather than on credit losses. The credit analysis process is performed differently these days and it is the development of this process that is the focus for the authors.This thesis is about the credit analysis process in the four largest banks of Sweden. The purpose of the thesis is to highlight which factors the banks include in the credit analysis process and in how small and medium size companies are treated in this process.

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

My thesis brings up the subject of power. In the 33 local authorities we have in Skåne, I have made a quantitative study, to see how many young people that are included in the power of politics, through local authorities parliament. This is the first of the two parts that I have devided my thesis into. The second part is qualitative and examines four young politicians, and their thoughts on holding a position that is so unusual to hold at their age. This is the basis for my analysis where I bring up age as a form of discrimination.

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Andelen flerspråkiga barn i Sverige ökar och följdaktligen så även behovet av kunskap om deras språkutveckling. Flerspråkiga barns språkutveckling har visat sig skilja sig i viss mån från den hos enspråkiga barn och då normer för flerspråkiga barns språkutveckling saknas i logopedisk verksamhet idag finns en osäkerhet kring hur deras språkutveckling bör bedömas. Föreliggande studie ingår i det internationella forskningsnätverket COST Action IS0804 och ämnar utgöra ett litet bidrag till en växande databank om flerspråkiga barns språkutveckling, i detta fall i jämförelse med enspråkiga barns språkutveckling. Studien utgår från 100 narrativer berättade av sex- och sjuåriga enspråkiga svensktalande och flerspråkiga engelsk-svensktalande barn. Narrativerna eliciterades med hjälp av två bildsekvenser från bedömningsmaterialet MAIN och samlades in inom ramen för tre tidigare magisteruppsatser i logopedi från Uppsala universitet.
